I had long thought Drupal's Views module could help power a photo gallery, but was daunted by the prospect of actually creating one. Happily, though, KarenS has created the Views Gallery module - which makes it relatively easy to start a gallery.
Note that Views Gallery requires other modules, too: maybe you should install these first, and Views Gallery once all is ok. (I write this after Custom Pagers not working for me; not sure why.)
Martin also sent me an email, and I've replied:
